LINK FOR JEWELRY, 84 0.

SPECIFICATION forming part of Letters Patent No. 462,916, dated November10, 1891.

Application filed March 2, 1891. Serial No. 383,411. (No model.)

To all whom it may concern:

Be it known that I, HENRY U. WILsoN, of W renth am, in the county ofNorfolk and State of Massachusetts, have invented a new and usefulImprovement in Links for Bracelets, Jewelry-Buttons, &c., of which thefollowing is a specification.

This inven tion relates to hollow links or shells used in bracelets,jewelry buttons, [0 (such as cuff-buttons) and other hollow articles ofjewelry, and it is particularly applicable to links or shells ofirregular shape.

The object of llllS invention is to produce a link of irregular shapewith a finished turned-in edge on its rear side. \Vhen the links areround or square it is not difficult to turn in the edges withoutaltering the thickness or construction of the link for the purpose; butwhen the link is of irregular shape it is impossible to turn in the edgeproperly and neatly unless the metal is made so thin that it is notstrong; enough for the main or central portion of the link, while if themetal is madeth ick enough to give sufficientstrength to the link it istoo thick to make a satisfactory turned-in edge.

The object of this improvement is to obviate this difliculty.

In the accompanying drawings, in which similar letters of referenceindicate like parts,

Figures 1 and 2 are perspective views of irregular-shaped linksembodying my improvement before the edges are turned in. Fig.

is a section of the link shown in Fig. l with the edge turned in andcompleted. Fig. 4 is a similar section taken before the edge has beenturned in.

The links A,instead of being made of even thickness throughout, havetheir main and central portions made of sufficient thickness forstrength by being formed in a die, While by means 01' a special plungera shouldera is formed and the stock between said shoulder and the edgeis made considerably thinner, as shown in Figs. 1, 2, and at. Thisportion 5 A is then bent by swaging or burnishing in a press or lathe,or byhand, if preferred, into the position shown in Fig. Thus the mainportion A is of suitable thickness for strength,

while the edge A is thin enough to be turned in neatly andsatisfactorily.

This improvementis valuable in connection with round or square links (inaddition to those of irregular shape) where the part to be turned in isdeep or long.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

The jewelry-link described, consisting, of the thick main portion A andthe thin edge 60 A turned in against the shoulder a, substantialiy asset forth.
